The Genie 55921GT Socket Head Cap Screw, 3/8-24 x 1.25 is a genuine OEM fastener built for Genie GS scissor lifts, the TZ-50 trailer-mounted articulating boom, and the Z-30/20 N articulating boom lift. As a direct OEM replacement, this screw is manufactured to the exact thread specification and dimensional tolerance Genie requires, ensuring it seats correctly in the factory-designed mounting location without rework. Cross-reference part number 55921GT against your machine's parts manual to confirm it is the correct fastener for your specific configuration before ordering.
Key Features
- OEM-Grade Fastener Integrity — Manufactured to Genie's exact 3/8-24 thread pitch and 1.25-inch length specification, with the dimensional conformity a socket head cap screw demands for consistent clamping force.
- Hex Socket Drive — The socket head cap design allows torque to be applied with a standard hex key in tight or recessed mounting locations where a conventional hex head tool cannot reach.
- Broad GS Scissor Lift Coverage — Fits a wide range of Genie GS scissor lifts, including BE, DC, AV, and standard slab-deck variants, as well as select Genie Z and TZ articulating boom models.
- Correct Fastener, Correct Clamp Load — Using the right OEM-specified screw maintains the design clamping load at the joint. An incorrect thread pitch or length can lead to joint movement, fastener fatigue, or damage to mating components.
- Genuine Genie OEM Part — Supplied as an authorized Genie OEM component, backed by the same quality and traceability standards as every other part Genie puts into production machines.
A socket head cap screw is a high-strength fastener with a cylindrical head and an internal hex socket drive, used where a low-profile head and precise torque application are required. On Genie aerial equipment, fasteners like this one secure structural, mechanical, and panel assemblies that must stay firmly clamped under the vibration and loading conditions of everyday machine use. A worn, cross-threaded, or incorrectly specified screw can compromise joint integrity, so replacing a damaged fastener with the correct OEM part — matched to the original thread pitch, length, and material grade — is the straightforward way to restore the connection to its designed condition.
